IMO all those examples are less readable than writing it in an imperative way using good function and variable names.
Also, len() is a Python convention and a built-in function that calls __len__() on that object. It’s even more established than .length in JS, so I really don’t see why someone would expect anything else. And even then, one could call my_list.__len__() if they really wanted to be sure and have that “left to right” bonus.
